High water temperatures combined with a wet environment make a perfect target for bacteria growth, which is why Great Barrier replacement spa filters are made by using Reemay Liberty with Microban

This exclusive product inhibits the growth of bacteria that causes stains, odours and the overall degradation of your cartridge filter surface, and because Microban technology is built right into the fabric, it cannot wash out !

Every Great Barrier cartridge is supplied with a set of stickers to place in your calendar, reminding you to clean your cartridge monthly and to replace it regularly.
